Dynamic evaluation and regulation of water carrying state using a coupled iterative method

The water carrying capacity and the state are two similar concepts, there no clear boundaries between them, so exists confusion during evaluation process. Additionally, current methods cannot meet dynamic change requirements under different control measures. This study emphasizes difference concepts points out that core of is determination thresholds. In contrast, a evaluation. A coupled iterative model proposed based on extended Fourier amplitude sensitivity test algorithm modified state-space method. order to evaluate regulate dynamically, calculation introduced into state. During process, resources in non-overloaded area allocated surrounding adjacent overloaded areas until resource original over-loaded reaches an acceptable level, total amount allocation multiple iterations given. this study, we take Jilin Province as research object. We hope coupling paper can be widely applied future.
